iIMPROVEMENT IN PERFORATING-STAMPS.

Specification forming part of Letters Patent No. 151,723, dated June 9,1874; application filed December 23, 1873.

To all lwhom it may concern Be it known that I, JOHN SIGWALT, Jr., of

Chicago, in the county of Cook and State of Illinois, have inventedcertain new and useful Improvements in Perforatin g-Stamps, of whichimprovements the following is a full, clear, and

Figure l is a side elevation of a hand canceling-stamp embodying myimprovements; Fig. 2, a top view of the platen; and Fig. 3, a verticalcentral section of the press or stamp. Like letters of referenceindicate like parts. Tickets canceled or particularly designated byhaving printed matter stamped upon them are capable of beingfraudulently altered by erasing such matter, and hand cancelingstamps,constructed to cancel or mark the tickets by pnnchin g them, have beenemployed for the purpose of preventing such alteration. My inventionrelates to the latter class of hand canceling-stamps; and consists incertain novel features, hereinafter fully described and particularly setforth, relating to the construction of the stamps, my object being toimprove their operation.

- In the drawing, A represents the base of the stamp, and B is ayielding arm attached thereto. C is the platen or table which receivesthe tickets. 'lhe platen consists of the plate or disk a, madepreferably of steel, and of the supporting-block a attached to theforward Aend of the base A. The plate a is attached to the block a', andis perforated, as shown at e. The perforations e e are arranged tocorrespond to the characters to be punched into the tickets, and may,for example, be so arranged as to approximate the word half, as shown inFig. 2, thus indicating that the ticket so which is arranged over theplaten. d d are punches projecting fromthe lower face of the block'D,and corresponding, in size, number,

and arrangement, to the perforations e c, the latterbeing just largeenough to receive the punches. E is a yielding plate or stripperattached to the lower face of the blockD, and perforated to receive thepunchesd d.

In' order to stampa ticket, it is arranged upon the platen so as tocover the perforations c e. The forward end of the arm B is then strucksuddenly with sufficient force to drive the punches through the ticket.The small disks which are thus cut from the ticket fall into the channele', and either fall away or may be readily relnoved. The plate E strikesVthe ticket before the punches do, and yields to the continued downwardmovement of the arm B.

When the arm B is released the ticket isv pushed from the punches bymeans of the plate F, and drops upon the platen. The ticket is thusfirmly held in place while beingpunched, and after it is punched it isentirely free from the stamp.

Having thus described my invention, what I claim as new, and desire tolsecure by Letters Patent, is-

The yielding arm, terminating at its forward end in the head or block D,provided with the punches d d and with the yielding perforated plate orstripper E, in combination with the base provided with'a platenconsisting of the perforated plate a and of the supporting-block a',having the channel e therein, substantially as and for the purposesspecified.
